CROWN-SEAL-CAP MACHINE.

Specification of Letters Patent.

.Patented Aug. 15, 1916.

Application led Hay 22, 1913. Serial No. 769,226.

' Be it known that I, JESSE W. NICHOLS, a citizen of the United Sta-tes, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Crown-Seal-Cap Machines, of which the following is a specication.

This invention relates to the retention 1n place within a closure cap or cover of a packing disk or gasket and, while susceptible of application to closures of diverse type, has to do'and is herein described 1n connection with the ,manufacture of what is generally known as the crown seal cork or Ihe invention has for its principal object novel means for securing the cork dlsk in place within the cap. Prior to the attachment of such closures to bottles the flanged corrugated cap is provided wlth an inserted packing disk usually of cork and some provision is required to be made for holding the disk in place. It has been proposed to interpose adhesive between -the top of the cap and the cork and by heating and simultaneously pressing the disk into contact witlrthe softened adhesive to effect an attachment between the disk and the cap. By my invention I avoid the disadvantage of having present an adhesive with the associated danger of deleteriously affecting the stored contents of the bottle and also reduce the expense of manufacture. by doing away with the labor and mechamsm necessary to the heating and pressing of the caps. I accomplish this result by indentlng the caps marginally upon the edge of the .1nserted disk so as to lock the same 1n position with the cap.

In the accompanying drawing and in the following detailed description based thereon -I set -forth my improved method and two forms of mechanism for carrying out thel same.

It is to be understood that the invention is capable of further modification without departure from the essence thereof or the sacrifice of its material advantages wherefore the drawing and description are to be takenpin an illustrative and not in an unnecessarily limiting sense.

In the drawing-Figure 1 is a front elevation showing the essential portions of a machine embodying the invention; Fig. 2 is a fragmentary irregular section illustrating th e operation ofthe machine; Fig. 3 is a similar view based upon modifications; and Flg. 4'is aside elevation partly in vertlcal section of a crown seal cap after passlng through the machine. I

Having particular reference to Figs. 1 -and 2 of the drawing, the reference numeral 1 1 designates the base of the machine supportlng a statlonary annular member 12 within which is concentrically mounted for' rotation a rotary member 13. The latter is provided with a peripheral groove 14 the bottom of which is formed with outwardly facing ribs or teeth 15 while the stationary member 12 is provided with an inwardly facing groove 16, the bottom of which is advantageously smooth. The walls of the two grooves may either be an integral portion of the members themselves,'or they may be formed of plates secured at the rear and 1n front of the ftwo members. Preferably, and as shown, the groove upon the inner face of the stationary member 12 does not extend entirely around the same but only through a small arc and is bounded in front by -a plate 17 removably attached to the member 12 by screws 18. Pricking pins "19 are mounted for radial adjustment in the rim of the member 12 with their points 20 pro- ]ectlng inwardly from the bottom of the groove a slight distance. The opposed grooves 14 and 16 together form an arcuate channel having a width substantially the same as the exterior diameter ofthe crown seal cap 21, which caps with their inserted packing disks 22 are fed to the upper portion of the channel in any approved manner as from a feed chute 23. As 'the caps drop into the channel the corrugations 24, which are ordinarily found in the side walls thereof, engage with the ribs or teeth 15 Vof the cork disk 22 and effectually prevent the dislodgment of the disk by the interlocking engagement betweenv the disk and the prongs.

In Fig. 3 is illustrated a substantial reversal of the arrangement, the adjustable pricking devices 19a being mounted radially throughout the periphery of the rotary member 13a while the stationary member 12a is provided upon its inner face with the ribs or teeth 15a. The operation in thetwo cases is substantially the same, the caps being transported through the channel and. 1provided in their passage with the inwardly projecting prongs caused by the upsetting of the metal by pins.

An insulating interlining is advantageously employed between thecork packing and `the top of the cap. It may consist of a parafflned sheet of paper to prevent chance contact between the stored liquid and the metal of the cap, or as another form of lining a suitable lacquer may be applied, to the inner face of the cap before the packing disk is inserted, in which case a lacquer should be employed which is chemically inert so that no action will take place between the lacquer and the metal, or Vbetween the lacquer and the liquid contents 0f the receptacle upon which the cap is used as a closure. In many respects the employment of a chemically inert lacquer is more desirable than a separate distinct lining and some such insulating medium is always desirable to efectually safeguard the cap and contents against injurious reactions.

I claim:

1. In a machine for securing .a packing within a closure cap, means to indent the wall. of the cap into peripheral engagement with the packing, said means comprising two members concentrically mounted to provide an arcuate channel between portions thereof, one of said members being rotatable and one of the members provided with radially disposed pricking elements, the channel adapted to receive the caps and transport the same therethrough in rolling contact with the opposed edge walls thereof, substantially as described.

2. In a machine for securing a packing disk within a crown seal cap, means to indent the wall of the cap to form spaced prongs inwardly 'projecting into peripheral engagement with the disk, said means comprising twoA members concentrically mounted to provide an arcuate channel between portions thereof, one of said members being rotatable and one provided with radially disposed pricking elements, the channel adapted to receive the caps and transport the same.therethrough in rolling contact dially disposed pricking elements and the other with teeth facing toward the channel, the channel adaptedto receive the caps and transport the same therethrough in 'rolling contact with theopposed edge Walls thereof, substantially as described l 4. In a machine for securing a packing disk within@ crown seal cap, means to indent the wall of the cap to form spaced prongs inwardly projecting into peripheral engagement with the disk,- said'means comprising two members concentrically mounted to provide an arcuate channel between portionsthereof, the inner one of said members being rotatable and one of the members provided with radially disposed pricking elements, the channel adapted to receive the caps and transport the same therethrough in rolling contact with the opposed edge walls thereof, substantially as described.

5. In amachine for securing a packing disk within a crown seal cap, means to indent the wall of the cap to form spaced prongs inwardly projecting into peripheral engagement with the disk, said means comprising two members concentrically mounted to provide an arcuate channel between portions thereof, the inner one of said members being rotatable and provided with radially projecting teeth and the othermember provided with adjustable radially disposed pricking elements, the channel adapted to receive the caps and transport the same therethrough in rolling contact with the opposed edge walls thereof, substantially as described.

In witness whereof Irhave hereuntoA attached my signature in the` presence 0f two witnesses.
